2003-10-13  Gary Thomas  <[e-mail]>

	* src/quicc_smc_serial.c: Add some I/O barriers to make sure that

2003-10-08  Gary Thomas  <[e-mail]>

	Reported by Tord Andersson <[e-mail]>

2003-03-31  Gary Thomas  <[e-mail]>

	* src/quicc_smc_serial.c (quicc_sxx_serial_init): Handle SCC3 on
	various processors (signal routing differs).

2003-03-28  Gary Thomas  <[e-mail]>

	* src/quicc_smc_serial.c: Change how buffers are allocated & aligned
	to a cache line - previous attempt wasted a huge amount of space.

2003-03-23  Gary Thomas  <[e-mail]>

	* src/quicc_smc_serial.h: Move common definitions to common
	include file (in HAL).

	* src/quicc_smc_serial.c: 
	* cdl/ser_quicc_smc.cdl: Remove options for baud rate generator
	assignment - use more generic [automatic] support.

2003-03-17  Gary Thomas  <[e-mail]>

	* src/quicc_smc_serial.h: 
	* src/quicc_smc_serial.c: 
	* cdl/ser_quicc_smc.cdl: Add support for SCC1/SCC2/SCC3.  Inspired
	by Paul Randall <[e-mail]>

2003-03-05  Gary Thomas  <[e-mail]>

	* src/quicc_smc_serial.c: Use common routines to manage CPM/DPRAM
	pointers - much nicer in a multi-driver environment.

2003-02-24  Jonathan Larmour  <[e-mail]>

	* cdl/ser_quicc_smc.cdl: Remove irrelevant doc link.

2002-12-10  Gary Thomas  <[e-mail]>

	* cdl/ser_quicc_smc.cdl: Only enable devices which exist - as described
	by the HAL/CDL interfaces.

2001-11-30  Jonathan Larmour  <[e-mail]>
2001-11-29  Christoph Csebits  <[e-mail]>

	* src/quicc_smc_serial.c:
        aligning buffer to cache lines,
        flushing buffer in cache before flushing the device.

2001-09-10  Jonathan Larmour  <[e-mail]>

        * cdl/ser_quicc_smc.cdl:        
        Fix 234000->230400 typo.

2000-12-22  Bj鰎n Stenberg <[e-mail]>

	* src/quicc_smc_serial.c (quicc_smc_serial_init_info): 
	Set quicc going only after most of the other initialization is
	complete - otherwise initializing too early causes some of the
	parameters not to be initialized properly.

2000-12-13  Daniel Lind <[e-mail]>

	* src/quicc_smc_serial.c (quicc_smc_serial_flush): 
	Don't mark a buffer ready unless it has been fully serviced - in
	particular, the interrupt bit must be clear.
	[2000-12-13] committed by Gary Thomas <[e-mail]>

2000-12-06  Jonathan Larmour  <[e-mail]>

	* src/quicc_smc_serial.c: Remove unread tx_enabled variable from
	quicc_smc_serial_info
	Ensure quicc serial interrupt is unmasked in general so that rx works!
	(quicc_smc_serial_start_xmit): Protect better from DSR interruption

2000-10-24  Jonathan Larmour  <[e-mail]>

	* src/quicc_smc_serial.c (quicc_smc_serial_ISR): Return with
	CYG_ISR_HANDLED (reported by Daniel Lind)

2000-08-01  Jonathan Larmour  <[e-mail]>

	* src/quicc_smc_serial.c (quicc_smc_serial_set_config): Now use keys
	to make more flexible.

2000-06-22  Hugo Tyson  <[e-mail]>

	* cdl/<yournamehere>.cdl: Remove the comment on the empty
	include_files directive; the tools now support this correctly.
	This keeps internal include files internal.

2000-04-11  Hugo Tyson  <[e-mail]>

	* cdl/ser_quicc_smc.cdl: Change the parent from CYGPKG_IO_SERIAL
	(which is enabled most of the time) to CYGPKG_IO_SERIAL_DEVICES
	(which is not...) thus allowing convenient control independent of
	platform.  Also enable all individual devices by default, now, so
	that they can be enabled simply by enabling the above new parent.

2000-04-07  Hugo Tyson  <[e-mail]>

	* ecos.db: Re-organize device packages.  This is a massive change
	involving deleting all the sources for serial and ethernet drivers
	from where they used to live in
	    packages/io/serial/current/src/ARCH/PLATFORM.[ch]
	    packages/net/drivers/eth/PLATFORM/current/src/...
	and reinstating them in
	    packages/devs/serial/ARCH/PLATFORM/current/src/...
	    packages/devs/eth/ARCH/PLATFORM/current/src/...

	All these new packages are properly defined in ecos.db, and are
	all of type "hardware" so that a "target" can grab them.
	
	This directory layout is descriptive of the devices we have right
	now, arch and platform are separate levels just to make it easier
	to navigate in the filesystem and similar to the HAL structure in
	the filesystem.

	It is *not* prescriptive of future work; for example, the mythical
	common highly-portable 16550 serial driver which works on many
	targets would be called "devs/serial/s16550/current", or a serial
	device for a particular board (cogent springs to mind) that can
	work with different CPUs fitted is "devs/serial/cogent/current".

	Changelogs have been preserved and replicated over all the new
	packages, so that no history is lost.

	The contents of individual source files are unchanged; they build
	in just the same emvironment except for a very few cases where the
	config file name changed in this movement.

	Targets in ecos.db have been redefined to bring in all relevant
	hardware packages including net and serial drivers (but the newly
	included packages are only active if their desired parent is
	available.)
	
	The names of CDL options (and their #defines of course) stay the
	same for the serial drivers, for backward compatibility.

	* templates/*/current.ect: these have had CYGPKG_IO_SERIAL added
	rather than it being in (almost) all target definitions.
	
2000-04-05  Jonathan Larmour  <[e-mail]>

1999-09-28  Hugo Tyson  <[e-mail]>

	* src/powerpc/quicc_smc_serial.c (quicc_smc_serial_init): Correct
	value supplied for interrupt priority - it may be unused, but it
	is asserted for range.  Initialize the diagnostic channel if on an
	MBX and if NOT using SMC1 ourselves, to ensure that diag output
	and built-in stubs work correctly; otherwise reset the quicc and
	ignore SMC1 as before.  Fix various warnings, mostly about
	casting/arg-passing/assigning away volatile.

	speed for this test.

	* tests/ser_test_protocol.inl: Removed 14400 baud tests for all
	MN10300 variants. The MN10300 cannot currently do this speed.
